Definitions

  • This invention relates to a connector comprising a casing having within the casing at least two groups of electrically conducting connecting elements led through a fixing piece and fixed to the fixing piece.
  • the connecting elements each have at one end a pin or a sleeve.
  • the pins and/or sleeves of each group are disposed at a distance from each other and parallel to each other and exposed to the environment in a respective coupling section.
  • An electrically conducting connection can be obtained with a corresponding group of matching connecting elements of another unit.
  • Respective conductors of a cable led into the casing from outside are connected to respective connecting elements.
  • the invention relates in particular to a connector for use in the field of seismic exploration.
  • Each group of the connector has two connecting elements.
  • a cable has two conductors which are connected to the respective connecting elements.
  • the connecting elements may be connected outside the connector to a string of geophones.
  • One coupling section of the connector may be coupled to another connecting unit which is connected to a main cable which leads to a measuring and control unit.
  • the other coupling section of the connector may be coupled to another connector, optionally via an extension cable provided with coupling pieces at the ends thereof.
  • a connector of this type is known from U.S. Pat. No. 4,445,741, the disclosure of which is incorporated herein by reference.
  • the conecting elements consist of two parallel rods disposed next to each other which each have a sleeve at one end and a pin at the other end.
  • the rods are fixed at a relatively large distance from the ends of the rods in the center of a fixing piece.
  • Each of the conductors are led in a loop through passages formed in the fixing piece and the ends of the conductors are fixed to the rods.
  • one of the two groups of connecting elements of a connector comprises only pins and another group comprises only sleeves.
  • one group of connecting elements comprises in this case a thick pin and a thin pin for two different polarities and the other group comprises a sleeve with large inside diameter and a sleeve with small inside diameter, respectively, for polarities which correspond to the respective pins.
  • the known connector has as a disadvantage the fact that it is not suitable for electrically connecting strings of geophones in series if a number of connectors are coupled to each other and each cable emerging from a connector is connected to a string of geophones.
  • the coupling sections of the known connectors are formed at the ends of the connecting elements formed by rods, if a number of connectors of this type are coupled in series, a corresponding number of strings of geophones being electrically connected with each other in parallel, a long rod of connectors merging into each other is produced.
  • the connecting elements in particular the sleeves, may easily be damaged under these circumstances by bending of the rod.
  • the present invention provides a connector of the above-mentioned type which distinguishes itself in that the groups of connecting elements are fixed at a distance from each other to the fixing piece in a manner such that all the pins and sleeves extend parallel to each other on one side of the fixing piece, and the connecting elements are connected at the fixing piece to conductor tracks provided on a printed wiring card.
  • a connector in accordance with the present invention a choice can be made from various printed wiring cards which each have different patterns of conductor tracks.
  • the pins and sleeves with the same polarity can therefore be connected via the conductor tracks to each other and to a respective conductor of the cable so that if a number of connectors are coupled together the strings of geophones connector to the respective cables are electrically connected in parallel.
  • the connecting elements of one polarity can be connected via a conductor track to each other and the connecting elements of the other polarity can each be connected to a respective conductor of the cable so that if a number of connectors are coupled to each other, the strings of geophones connected to the cables are connected in series.
  • the connecting elements of one of the coupling sections of the last connector in the series chain may be short-circuited, which may take place by means of a suitable pattern of the conductor tracks inside the said connector itself or by means of a suitable, separate, short-circuiting connector.
  • the connectors can all be coupled to each other close to each other, the connecting elements all being within a relatively small area, damage to the connecting elements when used in the field is reduced.
  • the connector is preferably constructed in such a manner that the casing consists of a base part and a closure part which are fixed to each other in a sealing manner and at the same time form a hollow cavity, the fixing piece being disposed in the base part and the cable being led into the cavity in a manner such that the conductors of the cable are connected in the cavity to the connecting elements and/or the conductor tracks.
  • the base part and the closure part are preferably to be detachably fixed to each other.
  • the connector is not only modular but also constructed in a demountable fashion, it being possible to replace defective parts thereof. Even if, as a result of too great a tensile force being exerted on the cable, the electrical connection of the conductors of the cable to the conductor tracks or to the connecting elements is disturbed, or if the cable outside the connector is damaged, these defects can be repaired with the connector being retained.
  • the cable may be formed by the connection cable of a single geophone or of a string of geophones, the said cable being cut to the correct length and can be connected directly, i.e. without coupling pieces, to the respective connecting elements inside the connecotr.
  • the connector is preferably constructed in the following manner.
  • the closure part consists of rigid material.
  • the closure part has a passage with a bearing edge between the cavity to be formed with the base part and the environment, for a rigid ring disposed in the cavity.
  • the section of the passage increases in the direction of the cavity.
  • a grummet of flexible material is disposed in the passage.
  • the grummet extends to outside the closure part and the section of the grummet inside the passage touches the wall of the passage.
  • the cable extends out of the cavity via the ring and the grummet to the outside.
  • the cable has a barrier piece resting on the ring which counteracts movement of the cable toward the outside.
  • the fixing piece has a tag extending through a recess of the printed wiring card.
  • the tag has an eyelet.
  • the conductors of the cable are wrapped with one or more windings around the edge of the eyelet.
